Scottish National Dictionary (1700–)

-LINS, -LINGS, suff. This suff., used to form advs., is much more freq. in Sc. than in Eng., where it survives only dial., occurring: 1. after nouns, to indicate “in the direction of” (the orig. usage) as in Arselins, Backlins, Eastlins, Grooflins, Heidlins, Sidelins; 2. with adjs. or quasi-adjs., similarly to connote direction and also manner, condition, degree.
